SPRING, Texas - A father opened fire at a suburban Houston home Wednesday, killing four of his children as well as two adults who were with them, and critically wounding his 15-year-old daughter, authorities said.

The teenager was able to call 911 and later warned deputies that her father planned to go to her grandparents' home to kill them, said Deputy Thomas Gilliland of the Harris County Sheriff's Office. The suspected gunman eventually surrendered after a three-hour standoff with deputies who had cornered him in a cul-de-sac.

The Sheriff's Department said precinct deputy constables were called to the house in the northern Houston suburb of Spring about 6 p.m. Wednesday and found two adults and three children dead. Another child later died at a hospital.

Killed were two boys, ages 4 and 14; two girls, ages 7 and 9; a 39-year-old man; and a 33-year-old woman, said Deputy Thomas Gilliland. The gunman and his wife are estranged, and she lives out of state, Gilliland said. All of the children were theirs. Two of the dead children were adopted, he said.

"It appears this stems from a domestic issue with a breakup in the family from what our witness has told us," Assistant Chief Deputy Constable Mark Herman told reporters.

Authorities did not release the identities of the victims or the suspect.

Authorities said the teen's information helped them intercept the suspect, who then led them on a chase, with nearly two dozen deputy constables' patrol cars following him into a cul-de-sac shortly before 7 p.m. There, the suspect's boxed-in vehicle remained for hours. Finally, about 10 p.m., the man emerged from his car, raised his hands and sank to his knees as deputies placed him under arrest.
